Most migraines are without aura. However, Migraine aura without headache is also quite common, and should be seen by an ophthalmologist to rule out more serious patholgy i.e. retinal detachment.  Migraine without aura is about twice as common as migraine with aura.

Migraine is diagnosed by determining whether some of a person's recurrent headaches meet certain criteria.

HISTORY
Headache lasting approximately 4-72 hours. The pain is unilaterall with pulsating, and sometimes includes nausea and/or vomiting . Of  moderate or severe intensity, which interferes with or prohibits normal daily activities.  The symptoms are aggravated by walking up or down stairs or other routine physical activity.
Usually including:photophobia
 

TRIGGERS

Caffeine,Tyramine, Tyrosine. Excessive release of Arachidonic Acid is a common trigger and is reversed by dietary adequacy of omega-6 & omega-3 fatty-acids. The ratio should be 2:1 Copper is also a trigger as is Serotonin, Alcoholic beverages, especially red wine. Caffeine is a very common trigger and other triggers include but are not confined to : Dairy products especially cheese, chocolate, onions, aspartame, citrus fruits, any processed foods and food derivites. Giving credence tat least in part to the ABO Blood Type, commonly met and excessively consumed avoidance foods must be considered. In the female, menstruation may be a trigger.

One thing is certain migraine attacks where pain is a symptom are the result of inflammation at the level of the PGE2  hormones. Migraine sufferers generally have a high Helper T-Cells: Suppressor T-Cells ratio.

TREATMENT
As with all chronic conditions, especially where allergy may be a causative factor, "Leaky Gut" must be considered. The herb Gingo Biloba is baseline therapy. Ginkgo Biloba has been shown in clinical trials to improve or cure  migraine headaches in 80% of persons. Gingko certainly relieves and prevents the ocular migraine, which is without pain and manifests as a saw-tooth flashing or brilliant shape usually in the peripheral vision. Other treatment includes more problem specific supplements including anti-inflammatories of which ProResolvin is First line Therapy, neuromuscular support, marine lipids, Phenolic Desensitization and food nosodes.
